# lines

This command takes a string from a pipeline as input, and returns a table where each line of the input string is a row in the table. Empty lines are ignored. This command is capable of feeding other commands, such as `nth`, with its output.

||
|
## Usage
|
||
|
```shell
|
||
|
> [input-command] | lines
|
||
|
```

```shell
|
||
|
> printf "Hello\nWorld!\nLove, nushell." | lines
|
